Piece Lets Your Phone Dual-Wield SIM Cards

If you have to use two phone numbers, you can either get two phones or one phone with multiple SIM card slots. Piece offers a third option: use your current iOS or Android device for both numbers. The credit card-size device lets you use a second SIM card via Bluetooth.

Piece works with micro- and nano-SIM cards for GSM networks. Once connected, all calls and SMS messages coming into the SIM card inside Piece go directly to your mobile device. The Piece app lets you send calls and SMS texts using the second SIM card. You can also manage your contacts through the app.

Piece’s battery lasts up to 150 hours on standby and is good for about four hours worth of talk time.

Pledge at least $75 (USD) on Kickstarter to receive a Piece unit as a reward.
